“…In hot climates, supplementing VA at a dosage of 16,000 IU/kg ( Abd El-Hack et al, 2017 ), or 9,000 IU/kg ( Lin et al, 2002 ), increased the reproduction of laying hens by raising the hatchability rate. In the same context, El-Husseiny (2018) concluded that broiler breeders had the best reproductive performances when given a diet rich in VA (12,500 IU/kg). According to Miao et al (2023a) , laying hens’ β-carotene deposition and bioconversion are examined; the results show no appreciable effects on egg quality, but supplemental doses increase β-carotene deposition.…”

“…In addition, given the increased demand for chicken meat, ongoing, effective, and targeted healthcare is required to prevent the spread of infections ( El-Saadony et al, 2023 ). The primary requirement to enhance successful poultry efficiency is the production of fertile eggs with a high hatchability ( El-Husseiny et al, 2018; Fu et al, 2022 ). In breeding poultry at advancing age, reproductive performance in breeding poultry is impacted by several variables, including oxidative stress and immune system imbalance ( Fouad et al, 2016 ; Wang et al, 2018 ).…”

“…Dietary VA has been gradually increased in poultry production to achieve higher performance. The productive efficiency of Cairo B-2 broiler breeders was increased when fed a diet fortified with VA at a level of 12,500 IU ( El-Husseiny et al, 2018 ). In geese breeding, VA increases egg quality by increasing immunoglobulin production, improving fertility and hatchability, and reducing MDA levels in the liver and ovary ( Fu et al, 2022 ).…”

“…Vitamin A in egg yolk is provided by the maternal diet. Adequate VA levels in poultry diet have been previously studied in chickens and ducks (Sklan et al, 1994;Yuan et al, 2014;Chen et al, 2016;El-Husseiny et al, 2018, Feng et al, 2019. We have investigated the appropriate VA supplementation levels in breeding geese diet, and the effect of maternal VA supplementation on the intestinal morphology of 7-day-old goslings in our previous study.…”

A 28-day experiment was conducted to evaluate the effects of dietary vitamin A (VA) levels on intestinal morphology and immune performance of goslings. Healthy, one-day-old goslings (360) of similar body weight were randomly divided into six groups fed diets supplemented with 0 (A), 3 000 (B), 6 000 (C), 9 000 (D), 12 000 (E), and 15 000 (F) IU/kg VA. Compared to group A, villus height in group D, as well as villus width and crypt depth in groups C and D were increased in the duodenum (quadratic effect, P < 0.05); villus height and villus width in groups B, C, D and E, and crypt depth in groups C and D were increased in the jejunum (quadratic effect, P < 0.05); villus height and villus width in groups C and D, and crypt depth in groups B, C, D, E and F, as well as muscular layer thickness in group D were increased in the ileum (quadratic effect, P < 0.05). Serum immunoglobulin A in groups B, C, D and E, and serum immunoglobulin G levels in groups D and E were higher than in group A (quadratic effect, P < 0.05). Serum interleukin-1 (quadratic effect, P < 0.05) and interleukin-6 (linear and quadratic effect, P < 0.05) levels in groups D and E, and serum interleukin-2 level (quadratic effect, P < 0.05) in group C were higher compared to group A. In conclusion, dietary supplementation with 6 000-9 000 IU/kg VA improved intestinal morphology and immune performance of goslings.

The objective of this study was to investigate the effects of dietary copper ( Cu ) on production, egg quality, and hatchability of Chinese Yellow broiler breeder hens and growth performance of their offspring. A total of 576 30-week-old hens were randomly allotted into 6 groups, each with 6 replicates (8 cages for each replicate with 2 birds per cage). The basal diet contained 3.50 mg/kg Cu, and the other 5 treatment diets contained 8.5, 13.5, 23.5 43.5, and 83.5 mg/kg Cu, respectively, additionally supplemented with Cu on the basal diet. The trial lasted for 15 wk. Qualified egg rate of birds fed 23.5 or 83.5 mg/kg Cu was significantly decreased ( P < 0.05) compared with those given 3.5, 8.5, or 13.5 mg/kg Cu. Plasma malondialdehyde concentration showed quadratic effect ( P = 0.002) which that decreased first then increased with dietary Cu increased. Highest values of Cu content and hepatic activity of Cu-ATPase occurred in hens fed 83.5 mg/kg dietary Cu with linear ( P = 0.001) and quadratic ( P = 0.001) effects. Shell strength and proportion on 18th day of live embryos of hens fed 13.5 mg/kg Cu were the greatest compared with other groups respectively ( P < 0.05); rate of qualified eggs for hatch and hatchability of fertilized eggs of hens fed 83.5 mg/kg Cu were the least ( P < 0.05). In conclusion, both inadequate (3.5 mg/kg diet) and excess (83.5 mg/kg) of dietary Cu can induce oxidative stress in hens and lead to decreased egg quality. Hatchability and growth performance of offspring were decreased when breeder hens were fed excess Cu in spite of greater hatching weight. The appropriate dietary Cu level for Chinese Yellow broiler breeder hens during the egg-laying period is 15.7 to 21.2 mg/kg (1.81–2.44 mg Cu fed per day) when based on Cu level and Cu-ATPase activity in the liver. This dietary Cu requirement is approximately doubled (∼40 mg/kg, ∼4.60 mg Cu per bird per day) for maximal response of eggshell thickness.
